Sierra Central Credit Union

People who live, work, or attend school in any of the 19 listed Northern California counties may join. Sierra Central’s business pages also use a geographic membership rule, but because those pages inconsistently say 18 and 19 counties without naming them, the exact business county list is inferred from the official personal disclosure.

“Membership open to all that live, work, or attend school in any of our branch location counties of Yuba, Sutter, Butte, Glenn, Shasta, Lassen, Tehama, Placer, El Dorado, Nevada, Amador, Colusa, Plumas, Sierra, Yolo, Sacramento, Alpine, Modoc, and Tuolumne.”
